Kelly has a ribbon that is 60 inches long. She cuts off 40% of the ribbon for an art project.while working on it,she decides she only needs 75% of the piece she cut off. How much ribbon does Kelly end up using in her project
Answer: She need 18 inches of ribbon for her project.
Step-by-step explanation:
Since we have given that
Length of ribbon = 60 inches
Part of ribbon cut off for an art project = 40%
So, Length of ribbon remains is given by
\(\dfrac{40}{100}\times 60\\\\=0.4\times 60\\\\=24\ inches\)
Now, Part of piece she only needs from cut off = 75%
so, Length of ribbon she need end up using in her project is given by
\(\dfrac{75}{100}\times 24\\\\=0.75\times 24\\\\=18\ inches\)
Hence, She need 18 inches of ribbon for her project.
